Mental health services data quality

These data are from the Mental Health Services Data Set (MHSDS), which reuses operational data produced by NHS and independent providers. The MHSDS data are known to be incomplete and are therefore an undercount at England level.

This report presents information about the quality of data and statistics published each month. This includes provider-level data quality information to help users understand the impact of local data quality issues. The purpose of this report is to support data quality improvement by making this information available in an accessible and interactive format.

Data is available from April 2016.

These statistics relate to complete calendar month reporting periods. Although it is possible to select part-month start and end periods in these visualisations, the statistics are not provided at this level of detail.

This visualisation presents a variety of data quality aspects which are included in the Mental Health Services Monthly Statistics publications.

The visualisation includes:

• the number of providers that submitted data to the MHSDS each month over a selected reporting period, and the total number of records submitted by them. MHSDS submission reports show those providers providing a submission compared to those NHS Digital consider to be in scope for the collection
• the volume of data submitted by each provider (coverage), by reporting period
• supplementary information about data quality submitted by providers in response to NHS Digital assurance activities
• 'VODIM' data validation rules around important data fields. These group data submitted by providers into one of five categories: Valid, Other, Default, Invalid, Missing

All providers of NHS funded specialist secondary mental health and learning disability services should submit data to the MHSDS. NHS Digital is working with partners to identify non-submitting organisations and improve compliance. 

To help interpret these visualisations, please refer to the MHSDS specifications and guidance.

Further information about the measures presented in the report are available in the Mental Health Services Monthly Statistics publications.

All values are rounded to the nearest 5, except values that are 4 or lower (including 0) which are suppressed to prevent the identification of individuals.

Figures produced by aggregation in this report may differ from those published as this report calculates totals as the sum of rounded figures.

Suppressed values appear as blank cells in tables and are not counted in rounded totals.

Percentages are based on pre-suppressed values and rounded to zero decimal places, except where the numerator is 0-4, where the percentage is suppressed.
